M'EANS FOR COUPLING CARS.

SPECIFICATION forming part of Letters Patent No. 231,565, dated August 24, 1880.

' Application led February 6, 1880.

To all whom t may concern:

Be it known that I, WILLTAM N. HAEING,

of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Means for Coupling Gars, of which the following is a specification.

My invention relates to the couplings used to unite the sections of hose or pipe of vacuum Io or air brakes carried by the cars, and to the couplings and draw-bars which are combined with said hose or pipe couplings to connect the several cars of a train when such hose or pipes are arranged within .the draw-bars, which are made hollow or open for the reception' thereof.

My invention consists in the combination of two draw-bars :adapted to lit one within the other, two pipes arranged concentrically within said draw-bars, and two yielding terminals for 2o said pipes adapted to be brought in end-to-end contact in coupling, and having one a concave and the other a convex face.

. Myinvention also consists in avalve of novel and simple construction for use in said hose or 2 5 pipe, and to be opened by the inward movement of the said yielding terminal.

My invention also consists in various details of construction and combinations of parts, fully hereinafter explained, whereby a very simple 3o and efficient coupling is produced.

In the accompanying drawings, Figure l represents a longitudinalv section through a combined car-coupling and hose or pipe coupling embodying my invention. Fig. Zrepresents a 3 5 similar section of said combined coupling after the yielding terminal of the hose or pipe coupling has been moved inward by coupling with a hose or pipe section carried by an adjacent car. Fig. 3 represents a transverse section on 4o the line x x, Fig. 2, and Fig. 4 represents a transverse section on the dotted line y y, Fig. l.

Similar letters of reference designate corre- .spondin g parts in all the figures.

A designates a portion of a car-coupling and draw-bar, connected to the car-body B by a king-bolt which should pass through the eye a at the inner end of said draw-bar, and free to swing sidewise upon aradius-bar, A, attached to the bottom of the car.

C designates the hose or pipe of a vacuum or 5o air brake passing under the car and extending through the draw-bar A, which is made open or hollow to receive it.

As here represented, the draw-bar is made externally and intern ally cylindrical, but portions of the sides thereof might be removed, or a draw-bar having its middle portion formed of plates, between which the hose or pipe O is arranged, might be employed.

The hose or pipe O is held rigidly in the draw- 6o bar against longitudinal movementin the present instance by a collar, b, upon the pipe, secured by screws immovablyin the draw-bar.

At the end of the hose or pipe C is a yielding terminal, C', having a telescopic connec- 65 tion with the end of the pipe (l, and adapted to be moved inward by contact with a yielding terminal, O2, carried by an adjacent car. The telescopic connection between the pipe O and the terminal C is here represented as 7o formed by an enlarged chamber, D, upon the inner end of the yielding terminal C', having a contracted neck portion, c, which ts over the pipe C, and has a suitable packing, d, to prevent leakage. This construct-ion might, if desirable, be reversed and the enlarged chamber D secured to the pipe C and t over the yielding terminal C.

In order to insure a tight face-to-face contact between the yielding terminal O and the 8o terminal O2, I have represented a spiral spring,

E, surrounding the terminal-'OQ and compressed as the said terminal is moved inward between the shoulder e on said terminal and the collar f, fixed to the draw-bar, and which 8 5 lits loosely upon the terminal C.

In order to insure the concentricity of the terminals O C2, I have represented them as respectively concave and convex upon their adjacent ends. 9o

The terminal C2 fits within a draw-bar, F, carried by an adjacent car, and made to lit within the end of the draw-bar A, and the said terminal is preferably pressed outward by a spring, g, in amanner similar to the terminal O.

To hold the draw-bar F in engagement with the draw-bar A, and to hold the two terminals C' C2 in tight face-to-face contact, I have represented a dog, G, pivoted to the top of the draw-bar A, and fitting in a circumferential groove or notch, h, in thc top of the draw-bar F, and extending partly around the same. The said dog has a segmental projection, which embraces nearly the semi-circumference of the draw-bar F, as clearly represented in Fig. 3, and hence has a very strong hohl upon the said draw-bar F.

To prevent the dog G from being accidentally displaced or raised by thejolting ofthe cars, I employ a latch, G', pivoted to the said dog and engaging with a notch,.s,in the drawbar, as represented. A cord, 1', or othertlexible connection, is attached to the latch and a pull on said cord or connection will first shift the latch G', releasing it from the notch in the draw-bar, and then raise the dog.

In order to prevent leakage of air or other motive agent the hose or pipe (l should be provided with a valve which is automatically closed as the yielding` terminal (5' moves outward, and opened as said terminal is forced inward iu the act of' coupling the cars. As here represented, said valve is formed by closing the end of the pipe G and making one or more holes,j, in the side of said pipe. Asthe terminal C is moved inward in the act of coupling the enlarged chamber l) is brought opposite the holes j, thereby permitting the free passage of air or other motive. agent through the coupled sections of pipe. As said terminal is moved outward bythe spring E the contracted neck c of the chamber l) fits over the holesj, and prevents the passage of air or motive agent from the hose or pipe C.

In order to prevent sudden jerks in starting and stopping cars the draw-bar A is constructed so as to yield by a pull outward and to cushion when forced inward. As here repsented, this is cli'ccted in the ibllowing manner: The draw-bar A has at its inner end an attached king-bolt connection or section, l', which is provided with the eye a for the kingbolt, and the said draw-bar A is capable of longitudinal movement in either direction relatively to the section B', subject to the action of a spring, H, interposed between them.

The portion IU of the draw-bar is composed of' two bands or sockets, l.' lr', made polygonalin this instance square-upon the inside, and connected by bars or plates l, extending from one to the other, and secured upon opposite Sides of said bands or sockets. The rear part, A2, of the section A of the draw-bar is connected to the main portion thereof by a screwthread, m, so as to provide for its ready detachment. The socket in which is the screwthread m is made externally polygonal-in this instance squareto tit within the band or socket k, and thc end n of the portion A2 is likewise square, and fits within the other square band or socket, k'. This precludes the draw-bar A from turning accidentally.

\The exterior of the piece A2 is round, ex-

cept at the end a, and upon itis placed a block, o, having a polygonal exterior fitted to the band or socket lr, and two polygonal washers, p p', iitting between the bars or plates I, and by them precluded from turning. The spring Il is placed between the washers p 71', and when a pull is exerted upon the draw-bar the washer p is held stationary against the bands or sockets k, while the other is moved forward by the square end u of the draw-bar, thereby compressing the spring H. When the drawbar is moved inward, as in coupling, the washer p' is held immovable against the band or socket k', while the other washer is moved forward by the block o, compressing the spring H in the other direction, as shown in Fig. 2. Thus violent jerks or jars in starting the cars arc obviated or lessened.

By my invention I protect the hose or pipe couplings of the brakes, and prevent their being injured; and as the hose or pipes arc coupled automatically' by the coupling of the cars, a saving of' time is effected, and no accidents can happen from a neglect to couple thc hose or pipes of the brakes.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination ot two draw-bars adapted to iit one within the other, two pipes arranged concentrically within said draw-bars, and two yielding terminals for said pipes adapted to be brought in end-to-end contact in coupling and having one a concave and the other a convex face, substantially as specified.

2. The combination, with the hollow drawbar A, of the hose or pipe C, arranged therein and stationary relatively thereto, and having its end closed and holes j in the side, and the yielding terminal C', provided with a chamber, D, fitting outside the pipe G, and comprising a contracted eylindric portion tightly fitting said pipe and adapted by its longitudinal movement to open and close the holes j, substantially as specified.

3. The combination of the draw-bar A and concentrically-arrauged pipes G C', the drawbar F, having a circumferential groove or notch, h, extending partly around it, and the concentrically-arranged pipe C2, and the dog G, pivoted to the draw-bar A, and having a segmental lip or projection for engaging with the groove or notch h, substantially as specitied.

4. The hollow' cylindrical draw bar composed ofthe section A, having the externallypolygonal socket m and the polygonal end a, of the section B', comprising the internallypolygonal bands or sockets la 7c', for preventing the turning of the sections relatively to eachother, in combination with the hose or pipe C, extending through the section A, substantially as specified.
